The usual formulation is 60% copper, 20% nickel and 20% zinc. However the composition varies as per consumer needs. Nickel silver is named for its but it, Silvery appearance is free from elemental silver unless plated. Higher amounts of copper make the nickel silver metal more ductile and more resistant to corrosion. Nickel makes the metal look more silverish and higher amounts of zinc improves lowers the, Corrosion resistance melting point and raises the durability and hardness it features many characteristics of brass differing only, And bronze in color. Nickel silver can take a high polish and hence is quite popular in jewelry making. Since the metal is hard and abrasion, Resistant, It has found usage in ball pen tips. It is ductile and, Highly malleable nonmagnetic. This makes the metal useful in manufacturing springs, Optical frames and parts. It is exceptionally durable against environmental corrosion and hence is perfect for soldering and welding.
